39986 Federal Register / Vol. 86, No. 140 / Monday, July 26, 2021 / Proposed Rules 

procedures the Administrator finds 

necessary for safety in air commerce. 

This regulation is within the scope of 

that authority because it addresses an 

unsafe condition that is likely to exist or 

develop on products identified in this 

rulemaking action. 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would not 

have a substantial direct effect on the 

States, on the relationship between the 

national Government and the States, or 

on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed, I certify 

this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

2. Would not affect intrastate aviation 

in Alaska, and 

3. Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document proposes to amend 

FAA Order 7400.11E, Airspace 

Designations and Reporting Points, 

dated July 21, 2020, and effective 

September 15, 2020. FAA Order 

7400.11E is publicly available as listed 

in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

Background 

The FAA published a notice of 

proposed rulemaking for Docket No. 

FAA–2020–0896 in the Federal Register 

(85 FR 69281; November 2, 2020) 

proposing to modify the Class D 

airspace McChord Field (Joint Base 

Lewis-McChord). Interested parties were 

invited to participate in this rulemaking 

effort by submitting written comments 

on the proposal. One comment was 

received during the comment period. 

The commenter was concerned that 

removing the entire area previously 

excluded for Spanaway Airport, would 

place aircraft arriving and departing 

Shady Acres Airport at a disadvantage 

while departing to the North and 

Landing to the South. 

Subsequent to publication of the 

NPRM, the FAA received comments 

from the Aircraft Owners and Pilot 

Association (AOPA), the Airport 

Manager and local Pilots from Shady 

Acres Airport and the U.S. Air Force. 

AOPA, the Airport Manager and local 

pilots were in favor of a small portion 

of airspace, from the original area cutout 

for Spanaway airport, being maintained 

for satellite airport operations at Shady 

Acres Airport. These amendments 

would maintain the current level of 

operational safety, while adhering to 

FAA policy on airspace for satellite 

airports. The U.S. Air Force was not in 

favor of this recommendation. In 

addition, the FAA identified an area of 

airspace to the Northwest that needed 

additional clarification in its boundary 

and the U.S. Air Force identified that 

only the VOR was being 

decommissioned and not the Tactical 

Air Navigation System (TACAN), as 

previously reported. The FAA 

determined that the proposal needed 

additional consideration due to these 

comments. 

The Proposal 

The FAA is proposing an amendment 

to 14 CFR part 71 by modifying the 

lateral dimensions of the Class D 

airspace. The FAA initiated a review of 

the assigned airspace and drafted the 

subsequent proposal for modification 

due to three actions. The FAA 

decommissioned the McChord VOR 

because the U.S. Air Force was no 

longer going to maintain the NAVAID. 


jbell on DSKJLSW7X2PROD with PROPOSALS
39988 Federal Register / Vol. 86, No. 140 / Monday, July 26, 2021 / Proposed Rules 

As a result of the decommissioning, the 

FAA was required to redefine the 

airspace that uses the VOR as a 

reference and remove the reference from 

the associated airspace descriptions. 

The U.S. Air Force requested 

elimination of airspace previously 

excluded for operations at Spanaway 

Airport. In response, the FAA 

completed an airspace review to 

evaluate that request and the Class D 

airspace had not been examined in the 

previous two years as required by FAA 

Orders. 

The exclusion of Class D airspace that 

is southeast of the airport would be 

modified to facilitate use of the airspace 

for aircraft arriving and departing Shady 

Acres Airport, in keeping with FAA 

Directives. A portion of the airspace 

overlying Lakewood, WA would also be 

eliminated, as it is no longer needed. 

In addition, the Legal Descriptions 

Heading would be corrected to identify 

the proper city and state, the name of 

the airport and the geographical 

coordinates for McChord Field (Joint 

Base Lewis McChord) to match the 

FAA’s National Airspace System 

Resource (NASR) database. 

Class D airspace designations are 

published in paragraph 5000 of FAA 

Order 7400.11E, dated July 21, 2020, 

and effective September 15, 2020, which 

is incorporated by reference in 14 CFR 

71.1. The Class D airspace designations 

listed in this document will be 

published subsequently in the Order. 

FAA Order 7400.11, Airspace 

Designations and Reporting Points, is 

published yearly and effective on 

September 15. 

Regulatory Notices and Analyses 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current, is non-controversial and 

unlikely to result in adverse or negative 

comments. It, therefore: (1) Is not a 

‘‘significant regulatory action’’ under 

Executive Order 12866; (2) is not a 

‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, would not have a 

significant economic impact on a 

substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

Environmental Review 

This proposal will be subject to an 

environmental analysis in accordance 

with FAA Order 1050.1F, 

‘‘Environmental Impacts: Policies and 

Procedures’’ prior to any FAA final 

regulatory action.
